The whole 'early adopters benefit too much so it's a ponzi scheme' is a load of bollocks, while I get your example, I've got an even better one, why does no one jump and down in a rage over people buying penny stocks and suddenly getting rich overnight holding them? Why does nobody attack people like Peter Schiff for example who said he bought gold back when it was $30 or so? It's the exact same thing with Bitcoin, people who invest in early are taking a huge risk and could easily lose it all, there's no real different from Bitcoin to anything else, it's just the technology behind it and as we've come to get used to the ignorant old morons on television just don't get that because it's too new to them so they go on a rabid attack.
I don't know why people act so surprised when they see people go after Bitcoin this much, we've seen it with the internet, we've seen it with games, we've seen it with 3D printing, I'm also sure that the older ones here will remember the time when rock music was considered the 'devils' music and the came up with all sorts of bullshit surrounding that as well. Ignorant old people will always fight the progress of humanity, it's a constantly repeating pattern.
So remember these lines when something new comes along and we're all old and don't get taken in by other peoples' bullshit:
. Rock music is devils music
. Violent video games corrupt our children and desensitize them to violence making them kill other people
. The internet is evil and it must be regulated to protect our children because child molesters use it etc.
. 3D Printing must be regulated because people can use it to make guns that kill people
. Bitcoin must be regulated because it's used by Terrorists and Criminals, they're taking a more diplomatic approach now and saying it 'can' be used by terrorists and criminals
Even longer ago here in the UK the church once banned football ( Soccer for you Americans ) and attacked it because they were terrified about how people were enjoying it more than going to church.
p.s. You don't buy Bitcoin because of the USD price, you buy it as a store of value and a convenient means of transferring wealth, people who buy it for other purposes are going to lose money.
